Unit Question: How have circuits impacted our environments?
INVESTIGATE: Define the following using this site: Webster's Dictionary Voltage:
electric potential or potential difference expressed in volts
Current:
a flow of electric charge; also: the rate of flow
Resistance:
the opposition offered by a body or substance to the passage through it of a steady electric current
Circuit:
the complete path of an electric current including usually the source of electric energy
Transistors:
a solid-state electronic device that is used to control the flow of electricity in electronic equipment and usually consists of a small block of a semiconductor (as germanium) with at least three electrodes
LEDs:
a semiconductor diode that emits light when a voltage is applied to it and that is used especially in electronic devices (as for an indicator light)
Capacitor:
a device giving capacitance and usually consisting of conducting plates or foils separated by thin layers of dielectric (as air or mica) with the plates on opposite sides of the dielectric layers oppositely charged by a source of voltage and the electrical energy of the charged system stored in the polarized dielectric
Resistor:
a device that has electrical resistance and that is used in an electric circuit for protection, operation, or current control
Switch:
a device for making, breaking, or changing the connections in an electrical circuit
*Digital Electronics:
-allows us to move a ton of information at one time
*Integrated Circuit:
contains hundreds of parts
~a complex set of electronic components that are on a tiny slice of semiconducting material
*Binary Code:
uses binary code (uses 0 and 1 to program computers)
*Circuit Breaker:
~protects houses, schools, and all buildings with electricity from an electrical overload
*Conductor:
anything that carries electricity

Using this site, answer the following questions:
1. Using one battery, make the light bulb work. a. Volts: 9.00 V b. Amps: .90 amps
2. Light two light bulbswith one battery. a. Volts: 4.50 V b. Amps: .45 amps
3. Using a switch to light one light bulb. a. Volts: 9.00 V b. Amps: .90 amps
4. Use a capacitor with your circuit. (One battery, one bulb) a. Volts: The capacitor powered the light bulb for just a second. b. Amps:
5. Use an inductor in your circuit. (One battery, one bulb). a. Volts: The inductor powered the light bulb only a little bit at first but then it powered it more. In the end: 9.00 V b. Amps: .90 amps
6. Use an AC Voltage in your circuit. What happens to the current? The power surges through. It quickly sends a burst of power then stops. Then the cycle repeats. a. Volts: -3.00 - 18.97 V b. Amps: 0 - 1.91 amps
7. Which items in the grab bag complete the circuit? (One battery, one bulb) a. Dollar Bill -NO b. Paper clip -YES c. Penny -YES d. Eraser -NO e. Pencil lead- Makes the current go... but so slow it doesn't light the light bulb f. Hand- NO g. Dog- NO
8. Use a resistor in your circuit. (One battery, one bulb) a. Volts: 4.50 V b. Amps: .45 amps
9. Add two batteries to light one light bulb. a. Volts: 18.00 V b. Amps: 1.8 amps
10. Add three batteries to the circuit. Right click on one of the batteries and change the voltage to 100%. What happens to your batteries? a. Volts: 117.98 V b. Amps: 11.8 amps
11. Make your own circuit a. Volts: b. Amps: c. Explain what happened with your circuit: d. Describe/draw your circuit below:

Answer the Following Questions After You Complete Your Circuit: 1. Did you like making the circuit? yes... even though I messed up twice! 2. What did you like the least about making the circuit? the complicated parts 3. What did you like the best about making the circuit? the end result 4. Using complete sentences, explain how circuits can be applied in the real world. (List three) Circuits are used in all technology! In every technology you can come up with. They make our lives easier.
5. Were you careful with the circuit, solder, and soldering iron? YES 6. Were you respectful and nice to other students? YES 7. Did you take a picture of both your circuits and add them to this wiki page? YES
ATTITUDE 1. Did you have a good attitude answering the questions? Explain: yes..... i was positive. 2. Did you have a good attitude making the circuits? Explain: I could have been better with this, because I was frustrated that I messed up and had to start over. 3. Were you a whiny baby during the circuit unit? Explain: NO... that would have been stupid. :)
